Question- Does the prologue count for the alarm/killing trophy?

This is a discussion on Question- Does the prologue count for the alarm/killing trophy? within the Deus Ex: Human Revolution forum, part of the D; I seem to be confused on the prologue and chapter 1 as to when this challenge actually starts. So does ...

There are alarms, which is the point. It's pretty stupid to be given a trophy for not setting off alarms when the alarms turning on is actually part of the story and can't be changed under any circumstances.

so if i reload a save before an enemy goes to an alarm panel, i won't be penalized at all either?

Nope, as long as you reload from that save and stop that enemy from activating the alarm panel, or not alert him at all. Deus Ex's platinum is all about saving often and watching your environment carefully. Good luck! =3

Follow-up question: Just started the game and going for Stealth. In my lower left corner of the HUD I often see a status like "suspicious" or even "hostile" (the first security camera / turret combination in the manufacturing plant for example). Does this constitute an alarm? I want to get across the way to get the hacking nuke, but I can't seem to get across without raising the level to "hostile". I tried to throw crates into the opening and sneak through behind them, but I'll still be seen...

It depends where actually.

I can answer part of your question; neither suspicious, nor alarmed from turrets, cameras or guards will trigger an alarm. With cameras, however it will if it turns hostile. Turrets don't count even if they're hostile. As long as no alarm panel is reached by guards you'll be safe.
